I get it that it requires yet-impossible materials to build a space elevator that goes all the way to space, but what if we instead build one that only extends high enough to clear the thickest layers of atmosphere, so rockets could be launched from there for massive fuel savings?

The space elevator would need to be strong enough to lift a rocket. Though, maybe without all that extra fuel they could be much smaller and lighter.
